Android: TextView, unicode character not shown properly

Question

I add a rating to a TextView programmatically by setting some unicode stars. It's the unicode star \⋆ , but the TextView shows me this character when I start the app: \⊠ .

This is how I created it:

private CharSequence calculatedSelectedRating(Integer rating)
{
    StringBuffer stringBuffer = new StringBuffer();

    //Star is ⋆ or \u22C6
    for (int i = 0; i < rating; i++)
    {
        stringBuffer.append('\u22C6');
    }

    return stringBuffer.toString();
}

and the result is what I set in TextView by setText(...) method.

Any ideas why this discrepancy occurs?

Answer 1

Some fonts don't support some characters. Check your message is shown with other font; include the ttf file on your assets folder, and set the content of the TextView with that font with something like:

yourTextView=(TextView)findViewById(R.id.idOfYourTextView);
Typeface font= Typeface.createFromAsset(getAssets(), "The_Font.TTF");
yourTextView.setTypeface(font);

Hope it helps.

Answer 2

尝试使用"代替'

stringBuffer.append("\u22C6");

Answer 3

On your TextView, you can use HTML format to set the text. Do something like this

mTextView.setText(Html.fromHtml(text));
